Add hardware to the system is done the same way for all device – you scan the QR code on the back of the device via the camera. I recommend – starting with your hub, then adding sensors and shutoffs.
NOTE: Add shutoffs BEFORE the plumber installs them, just in case they don’t work!
First, click on the [-] symbol (I think that’s supposed to be a view finder):
Next, scan the QR code:
Name the device (it really helps to name the sensors something like “Kitchen sink”, and then write that on the sensor with a sharpie)
Be sure you tell the system to turn the water off when a sensor detects moisture.
